Galaxy Superclusters Detected in the Modified PF-Catalog Using the FOF Method
Open Astronomy, 2011 The Modified Catalog of Galaxy Clusters and Groups (Panko & Flin 2006, PF), covering an area of 5000 square degrees in the southern sky, was used as the input for the search of galaxy superclusters.

ON THE DETERMINATION OF GALAXY STRUCTURE ELLIPTICITY
Odessa Astronomical Publications, 2007 We discuss factors influencing the determination of the observed shape of galaxy clusters when the covariance ellipse method is involved. The analysis of 377 Abell clusters show that at greater distances from the cluster center the ellipticity is rather ...

3D-Matched-Filter Galaxy Cluster Finder I: Selection Functions and CFHTLS Deep Clusters [PDF]
, 2009 We present an optimised galaxy cluster finder, 3D-Matched-Filter (3D-MF), which utilises galaxy cluster radial profiles, luminosity functions and redshift information to detect galaxy clusters in optical surveys.

Occurrence of radio halos in galaxy clusters - Insight from a mass-selected sample [PDF]
, 2015 Giant radio halos (RH) are diffuse Mpc-scale synchrotron sources detected in a fraction of massive and merging galaxy clusters. An unbiased study of the statistical properties of RHs is crucial to constrain their origin and evolution.

Cluster detection from surface-brightness fluctuations in SDSS data [PDF]
, 2001 Galaxy clusters can be detected as surface brightness enhancements in smoothed optical surveys. This method does not require individual galaxies to be identifiable, and enables clusters to be detected out to surprisingly high redshifts, as recently ...

On the origin of the intracluster light in massive galaxy clusters [PDF]
, 2015 We present a pilot study on the origin and assembly history of the ICL for four galaxy clusters at 0.44 0.2 L* and that neither dwarf disruption nor major mergers with the BCG alone can explain the observed level of luminosity and remain consistent with ...

Morphological Distribution of Galaxies in Some Nearby Clusters
Open Astronomy, 2019 We study the morphological distribution of galaxies in some nearby clusters, using the Sloan Digital Sky Survey – Data Release 9 (SDSS-DR9). The segregation between early-type galaxies and late-type ones is investigated in g – r / u – g color space ...

Detection of a Star Forming Galaxy in the Center of a Low-Mass Galaxy Cluster
, 2018 Brightest Cluster Galaxies (BCGs) residing in the centers of galaxy clusters are typically quenched giant ellipticals. A recent study hinted that star-forming galaxies with large disks, so-called superluminous spirals and lenticulars, are the BCGs of a ...

The Hydrangea simulations: galaxy formation in and around massive clusters [PDF]
, 2017 We introduce the Hydrangea simulations, a suite of 24 cosmological hydrodynamic zoom-in simulations of massive galaxy clusters (M200c = 1014–1015.4 M⊙) with baryon particle masses of ∼106 M⊙.
